Description

Technical Field

[0001] The utility model relates to the technical field of food production, in particular to an anti-collision buffer device for feeding and dropping baking trays. Background Art

[0002] With the upgrading of consumption, baked goods are becoming increasingly common in people's daily lives, which has also propelled my country's baking industry onto a fast track of development. Baked goods are increasingly being produced in factories and assembly lines. During the pastry production process, finished pastries are placed on baking trays and then baked in the oven. Baking requires high temperatures, and factories typically separate baking and pastry tray loading in separate workshops. Therefore, pastry tray loading and post-baking must occur in two separate areas. Therefore, the baking trays need to be recycled and transported via conveyor belts to the various pastry tray loading workshops.

[0003] During the recycling and transportation process of the baking tray, there will be two upper and lower conveyor belts. The baking tray needs to fall from the upper conveyor belt to the lower conveyor belt for transportation. The long-term and multiple falls will cause the baking tray to be severely deformed. Utility Model Content

[0004] In view of the problems existing in the above background technology, the utility model provides a baking tray feeding and dropping anti-collision buffer device, which can buffer the falling speed of the baking tray and prevent the baking tray from being deformed due to falling impact.

[0006] The falling buffer device includes a seesaw, a support column, a counterweight, a spring and a limiting rope. The middle part of the seesaw is hinged to the support column by a hinge shaft and can swing relative to the support column. When the seesaw is in a horizontal state, it is at the same height as the accelerating feeding disc conveyor belt; a counterweight is installed on the side of the seesaw away from the accelerating feeding disc conveyor belt, and a spring is installed under the other side of the seesaw. When the seesaw is in a horizontal state, the spring is in a free state, and one end of the limiting rope is connected to the two side edges of the seesaw on this side, and the other end of the limiting rope is fixed to the support column. When the seesaw is in a horizontal state, the limiting rope is in a straightened state, so that the seesaw on the baking tray side will not tilt higher than the height of the accelerating feeding disc conveyor belt.

[0007] Furthermore, the limiting rope is movably connected to the connecting end of the seesaw, and a hook is provided on the connecting end of the limiting rope, which is hung on a ring provided under the seesaw.

[0008] Furthermore, the counterweight is fixed to the rocker plate by bolts.

[0009] Furthermore, the counterweight block is made of magnetic material. When adding a counterweight block, it is only necessary to attach the mounting block to the front counterweight block through magnetism.

[0010] Furthermore, a slide groove is provided on the seesaw, and a bolt passes through the slide groove and is fixed to the seesaw; the bolt moves back and forth in the slide groove, and the distance between the counterweight block and the support column can be adjusted.

[0011] Furthermore, a blocking block is provided on the side of the seesaw supporting the baking tray to prevent the baking tray from moving forward due to inertia.

[0012] Furthermore, the blocking block is made of elastic material, and mainly serves as a safety blocking and protection function to prevent the baking tray from being damaged.

[0013] The technical effect of the utility model is that: the utility model provides a baking tray feeding and dropping anti-collision buffer device, in the process of the baking tray falling from the upper conveyor belt to the lower conveyor belt, a drop buffer device is set, through the principle of seesaw, to provide a buffer for the falling baking tray, and at the same time, in order to fall smoothly, a certain speed is required when the baking tray enters the drop buffer device, and an accelerating tray feeding conveyor belt is set in front of the drop buffer device to give the baking tray a certain speed, so that the baking tray can smoothly pass through the drop buffer device and fall to the lower conveyor belt, thereby preventing the baking tray from being deformed by impact caused by direct falling.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific Figures 1-3.

[0019] Reference Figure 1-2 As shown, the utility model provides a baking tray feeding and falling tray anti-collision buffer device, comprising an upper conveyor belt 1, an accelerating tray feeding conveyor belt 2, a falling buffer device 3 and a lower conveyor belt 4; the accelerating tray feeding conveyor belt 2 is arranged in front of the upper conveyor belt 1, and the accelerating tray feeding conveyor belt 2 and the upper conveyor belt 1 are on the same horizontal plane, the falling buffer device 3 is arranged in front of the accelerating tray feeding conveyor belt 2, and the lower conveyor belt 4 is arranged below the falling buffer device 3, and the transmission directions of the lower conveyor belt 4 and the upper conveyor belt 1 are opposite;

[0020] like Figure 3 As shown, the falling buffer device 3 includes a seesaw 31, a support column 32, a counterweight 33, a spring 34 and a limiting rope 35. The middle part of the seesaw 31 is hinged to the left and right support columns 32 through a hinge shaft 36, and can swing relative to the support columns 32. The counterweight 33 is installed on the side of the seesaw 31 away from the accelerating feeding disc conveyor belt 2, and the other side is used to receive the baking tray 100 transported by the accelerating feeding disc conveyor belt 2. A spring 34 is installed under this side of the seesaw. One end of the limiting rope 35 is connected to the two side edges of the seesaw 31, and the other end of the limiting rope 35 is fixed to the support column 32. When the seesaw is in a horizontal state, it is at the same height as the accelerating feeding disc conveyor belt, the spring is in a free state, and the limiting rope is in a straightened state.

[0021] The limiting rope 35 is movably connected to the seesaw 31. A hook 351 is attached to this end of the limiting rope 35, which hangs on a ring 310 below the seesaw. During counterweight adjustment, the limiting rope and seesaw are disconnected to facilitate leveling. A stopper 37 is provided on the baking tray side of the seesaw 31 to prevent baking trays conveyed by the accelerated tray conveyor from continuing forward due to inertia. The stopper 37 is made of an elastic material to reduce the impact force on the baking tray.

[0022] like Figure 3 As shown, the counterweight 33 is fixed to the seesaw 31 via bolts 38. The counterweight 33 is made of a magnetic material, making it easy to add or remove the counterweight during the adjustment process, thus facilitating equipment commissioning. A chute 39 is provided on the seesaw 31, through which bolts 38 pass to secure the seesaw 31. The bolts 38 move back and forth within the chute 39 to adjust the distance between the counterweight 33 and the support column 32.

[0023] like Figure 1-2As shown, when the baking tray 100 has not yet slid onto the seesaw 31, both sides of the seesaw are in equilibrium and are on the same level as the accelerating tray conveyor 2. The baking tray, conveyed by the upper conveyor, is accelerated by the accelerating tray conveyor and then enters the drop buffer. Due to the action of the drop buffer, the baking tray slowly falls onto the lower conveyor, which then carries the baking tray in the opposite direction.

[0024] The working principle is as follows: before use, the drop buffer device should be adjusted first. By adjusting the weight of the counterweight block and the distance from the support column, the seesaw can be kept in a horizontal state on both sides; after the adjustment is completed, the conveyor belt can be opened, and the baking tray conveyed by the upper conveyor belt is accelerated by the accelerating tray conveyor belt and enters the seesaw in the drop buffer device. The seesaw on the side that supports the baking tray drops due to the gravity of the baking tray. The spring underneath buffers the speed of descent and prevents the seesaw from hitting the lower conveyor belt too hard. When the baking tray enters the lower conveyor belt, the lower conveyor belt moves in the opposite direction, bringing the baking tray out of the seesaw, and the lower conveyor belt carries the baking tray to the opposite direction.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
